a novel horizontal wheel for a nuclear power station ring crane comprises an upper cover plate, an upper end fastening bolt, a wheel body, a conical outer sleeve, a lower end fastening bolt, a lower end positioning ring, a lower cover plate, a fastening bolt, an upper positioning ring, a spline inner sleeve, a self-aligning roller bearing, a spacer ring and a jackscrew; the cone-shaped outer sleeve is provided with a jackscrew, so that the cone sleeve is convenient to detach from the wheel body; fastening through a lower end fastening bolt; the lower end positioning ring is arranged at the inner side of the conical outer sleeve; two self-aligning roller bearings at the lower end are assembled inside the outer sleeve, the middle of the outer sleeve is separated by a spacer ring and is installed in a spline inner sleeve, and the spline inner sleeve is matched with the horizontal wheel shaft; an end cover is assembled at the upper end of the wheel body and is fastened by bolts; a positioning ring is arranged at the upper end of the outer edge of the spline, the thickness of the positioning ring is consistent with that of the end cover, and the upper end of the bearing is ensured to be positioned on a plane; the end cover is provided with an observation hole; and mounting a lower cover plate, and screwing the fastening bolt.
The invention has the beneficial effects that:
[1] the horizontal wheel for the nuclear power station ring crane can effectively realize observation of the condition of the bearing inside the horizontal wheel under the condition of not disassembling;
[2] the horizontal wheel for the nuclear power station ring crane can be used for rapidly disassembling and assembling the bearing, and is convenient to maintain;
[3] the horizontal wheel for the nuclear power station ring crane can ensure the assembly precision by adjusting the moment;
